If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Key takeaways

  • The most efficient car in the Two Seaters class for the 2020 model year is the Fiat 124 Spider at 29 MPG.
  • EPA estimates this car costs around $5,750 more in fuel over five years than an average new vehicle of the same model year.
  • Requires premium gasoline, which typically adds about 40 to 60 cents per gallon to the EPA's annual fuel cost estimate.

Fuel economy at a glance

These are the EPA's official ratings for the 2020 Nissan 370Z Roadster. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

Combined MPG 21 MPG
City MPG 18 MPG
Highway MPG 25 MPG
Annual fuel cost $3,300
Tailpipe CO₂ 429 g/mi
Fuel type Premium

How the 2020 Nissan 370Z Roadster compares

The 2020 Nissan 370Z Roadster returns 21 combined MPG. Cars in the Two Seaters class for the same model year average 18.9 MPG, which puts this car ahead of the class average by about 11%.

The most efficient car in the Two Seaters class for the 2020 model year is the Fiat 124 Spider at 29 MPG. The bar chart below puts the Nissan 370Z Roadster alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2020 model year (across all classes) returns 27.2 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2020 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 714.3 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,650
Average driver, 15,000 miles per year $3,300
Heavy driver, 25,000 miles per year $5,500

Specifications

The 2020 Nissan 370Z Roadster runs a 3.7-liter 6-cylinder engine paired with a automatic (s7), sending power through rear-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
